MEANS FOR CONTROLLING AND. REVERSING VESSELS.

Application filed September 24, 1924., Serial No. 739.602. and. in Sweden October 24, 1923.

This invention has for its object improvements in such controlling and reversing means for propeller-driven vessels that consists of a number of plates behind the propeller, normally folded together to form a common rudder, but that upon changing of the speed or reversing of the vessel are unfolded, so as to form an obstacle to the current from the propeller and wholly or partly force the water current to deflect and return, thus causing the vessel to reverse or change its speed without at the same time reversing or changing the speed of the motive power agent; and the objects of my improvements are to provide such a construction that the heavy resistance caused by the pressure of th water upon the rudder plates atthe opening or closing of the rudder is eliminated as nearly as possible; at the same time providing an uncomplicated mechanism for the opening and'elosing of the rudder; and a rudder that in its normally closed position will be of such a shape as not to lower the normal speed of the vessel.

In the accompanying drawing illustrating by way of example the present invention Fig. 1 shows a side elevation of a reversing rudder in normal or closed position;

Fig. 2 shows the same in plan View seen from above;

Fig. 3 is a section of the rudder on the line 11-11 of Fig. 1;

Fig. 4: shows the rudder in plan in fully expanded position; and

Fig. 5 in plan in partly expanded position.

Similar numerals refer to the same parts throughoutthe several views.

The reversing rudder, which is to be at tached to the stern portion of the hull of a vessel in the usual way, comprises two V61" tical rudder plates or steering plates 1 and 2. the upper and lower edges of which are bent, abutting against each other, when the rudder is collapsed. so that a space is en closed by the plates. The plates 1 and 2 are hingedly connected to triangular plates, i. e. at the top to the plates 3 and 4 and at the bottom to the plates 5 and 6 respectively. l l hen the rudder is collapsed the triangular plates are housed in the space between the rudder plates 1 and 2, the upper plates with their point directed in downward direction and the lower plates with their point upwards, see Fig. 1). The hinged connection plates may be of any suitable kind. As shown on the drawing, the triangular plates may be provided along one of their edges with two or more projections 29, entering corresponding openings in the rudder plates and locked to the latter on their outside.

The two triangular plates 3 and 4: are connected by a universal joint 13, 14 (see Figs. et and 5), .and the plates 5 and 6 are inthe same way connected by auniversal joint. The points of the triangular platesare cut away to provide space for the universal joints. 7 I 11 and 12 are twocoaxial rudder shafts of which 12 is hollow and encloses the upper part of the solid shaft 11. 7

Along a vertical line through the centre of gravity or its neighbourhood the rudder plates 1 and2 are pivotally connected by means of a journal pin 9 and 10 respectively with an arm or lever 7 and 8 respectively, which are rigidly connected, the arm? to the hollow shaft 12 and the arm 8 to the shaft 11. The arms 7 and 8 are each provided with a stop 28 and 27 respectively. 30 is a sleeve placed around the shaft 11 in the prolongation of the hollow shaft 12, to form a support against the sole piece.

Astern of their centres of gravity the rudder plates are connected by hinged links 17 and 18, each of the latter pivoting in bearings 31 and 32, attached to the plates. The links 17 and 18 are pivotally connected by a suitable device 33. lVhen the rudder is closed, the links lie collapsed backwards (see Fig. 1) in the chamber between the rudder plates, while in the reversing position they are fully stretched between the rudder plates in the oblique position the latter then occupy (see Fig. 4L),keeping their rear edges close against each other. To prevent the links from turning forward in the closing action of the rudder the ends 34, 35 of the links are bent over.

Rigidly attached to each of the rudder shafts 11 and 12 at the top are respectively toothed sectors 19 and 20 in mesh with spur gears 21 and 22 respectively, each rigidly connected to a chain wheel or the like 23 and 2 1.1 Arranged between the toothed sectors.19,-2O and the spur gears 21, 22 is a bar 25, one end of which loosely embraces the rudder shaft 11, while the opposite end is attached to some part of the hull of the vessel in any suitable way (not shown).
